j! mon use at the present time presents numerous objections, in that the valve seat 1s subv Patented Oct. 1,8, 1932 UNITED STATES PATENT orrlcEN JACOB L. BAUER, F WA'UWATOSA, WISCONSIN, ASSIGNOR OF FIFTEENVPER CENT T0 ARNOLD BAASCH, 0F lVlIIAUKECE,A WISCONSIN, AND 4'IWEN'lY-IEIYE PER CENT ',llO LOUIS REU'NZEL, OF WA'UWATOSA, WISCONSIN p rLoAr VALVE This invention pertains to floatl valves, such as are used in flush tanks for toilets and the like.

The conventional type of float valve in comject to rapid wear and cutting, requiring replacement of the entire valve. Also, due to the fact that the valve seat is embodied in the valve casing, expensive machine operations are necessary, and repair or replacement of the parts requires an awkward operation.

It is, therefore, primarily the object of the present invention to provide a comparatively simple, inexpensive, and efficient valve of the 1 foregoing type, in which the valve seat is formed separately of the valve casing to permit ready replacement should ,the same become worn or cut, thus materially increasing the life of the valve and eliminating necessity of replacement of the entire unit. l

Incidental to the foregoing, a more specific object resides in the provision of a detachable valve seat which serves as a coupling for connecting the valve casing with a supply pipe, and which is provided with a pair of seats available by merely reversingthe coupling, thus eliminating frequent replacement and facilitating repair of the valve. Y

lith the above and other objects in view, which will appear as the description`pro ceeds, the invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

In the accompanying drawing is illustrated one complete example of the physical embodiment of the present invention constructed accordingto the best mode so'far devised for the practical application of the principles thereof. l

In the drawing, the single view is a vertical section taken through a valve constructed in accordance with the present invention, and

assembled upon a supply pipe.

Referring n ow particularly yto the accom- 1931. Serial No.. 531,510.

panying drawing, in which the invention is Vshown applied to conventional flush vtank apparatus, the numeral 1 designates a supply "pipe upon which the iioat valve '2 is mounted in the mannery to be hereinafter described.

Y The valve 2 comprises a casing 3 provided with an outlet spout 4 having threaded therein the usual discharge pipe 5. In addition to thedischarge pipe 5, the spout 4 is also provided withan additional outlet boss 6 for reception of the conventional refill pipe 7, the same being disposed at an angle to clear the iioat rod and yalso facilitate discharge of a portion of the water supply therethrough.

The lower end of the casing 3, which is open to providean inlet for the water supply, is enlarged at 8 to provide an internal shoulder against which is abutted aV spider washer 10 that serves as a bearingfor the intermediate portion of the valve plunger The upper end of the valve plunger 11 Lis provided with an enlarged cylindrical head l Journalled in the opening 13 provided in the Y topjof the casing 3. casing 3, upon opposite sides of the head 12, are a pair of ears 14 between which a cam lever 15 is pivotally mounted, the cam lever A15 having threaded 1therein a conventional `float rod 16 which carries the usual ball float, not shown. Disposed overv the ears 14 is a splash cap 17 provided with a vertical slot 18. which straddles the camlever 15. A bolt 19 passes through the ears 14, the cam lever 15, and the cap 17 serves to assemble the same in operative position. f As will be noted, the upper end of the head 12, which is engaged by the cam lever 15, is rounded to provide smooth action, and reduce friction between the two.y

'n lhread'ed into the enlarged portion 8 of the casing 3 is a coupling 20 of similar construction at its opposite ends, whereby the same may be reversed whennecessary 0r desired. Each of the outer ends is provided with an internal annular shoulder 21 which, when as`- sembled in the, casing 43, receives the spider washer 10 and bindsthe same against the shoulder 9. Each end of theV coupling is lprovided with a recess 22, while the interrojecting upwardly from the top ofthe i mediate portion 23 is provided with a central bore 24 through which the valve plunger 1l projects, while surrounding the ends of the bore, the recessed portions are provided with annular raised seats 25, one of which cooperates with the valve 26 carried by the lower end of the plunger 11.

As will be noted from the drawing, .the bore24-iisofgreaterdialnetervthanthe plunger 11tlhus 4permitting freepassage of water through the bore when the valve is open.

In order to attach the coupling 2O tothe supply pipe l, the latter is providedwith` a ange 27, upon which a libre or other suitable washer 28 is se\ate d, Supportedupon the washer 28, and engaged by the lower end .ofthe coupling 20, is a screen A29, which serves Y f to eliminate particlesvof` grit and dirt from the water supply, t-hus preventing cutting and wear of the valve seats 25.

.which permits the entire valve unitV to be taken out for repairor replacement of parts. In order toremove the valve plunger from the c oupling20, the valve-2 6, carried by the lower end of the plunger, comprises a Washer Bleofxfibrous or other material, held upon lthe reduced yportion 32 of the shank ll by a .threadedcup 38,.which in turn is locked upon the shanlr32by means of a-nutal. Thus, in ,O rder; to assemble.; the valve7 it is merely necessary yto run -otfl-the-nut tland the cup 33, which permits the plungertobe-withedrawn, and in ordertofacilit-atesuch, action, the ,head l2' is provided with arropening 35 :fort reception of-arpin or other suitable! tool,` for holding the shankv againstA ro- -tftionwhile the nut and'caparebeing-run o .Y

lneoperation, a-spring36,-mounte'd on the plunger l1 sbetween the-head l2and the spider 10,;serves toinormallyhold thevalve 26 upon lits seat.`

Enom thevtoregoing explanation taken in connection with the accompanyingdrawing, bfs; believed: that'. the .operation and ,advantages otthe `present structure will'be quite apparent, n that. the plu-nger 11, which carries the valve 26, controls thesupply opening 24 :in, the coupling 2O .andisheldupon, its seltrby mea-ns. Aoff the4 spring V36,A untill such timel as pthewater.l level Within the tank (not shown) isloweredto provide for rockingof the cantilever 1 5,whichvdepresses the plunger againstthespringand opens the valve 26. It willalso be .appreciated that in providing a separable val-ve seat inthe form of a coupling, thesame eliminates-close machin- -arranoied between thepipek and uniting the same together, the coupling comspaced annular infr operations on the valve casing and provides for ready replacement of the seat in the event of wear.

Also, the provision of a pair of seats materially extends the life of the coupling, in l and described in considerable detail, itis to be understood that the salient feature of the invention resides in the' separable coupling provided with a pair of valve seats selectively availablefforsuse, and the coupling serving to carry the valve casing, whereby upon detachment of the coupling from a supplypipe, the entirevalve-unit is-readily removed.

Iclaim:

In a. float valve, the combination, a supply pipe, a-casing, a valve body having a stem, a guide for thestem, and a reversible coupling casing for prising an intermediate body Vhaving an axial `bore therethrough, opposed valve seats formed on the opposite ends-of the body'surrounding the bore and forming acontinuation the-reof, and Vexternally threaded -llanges formed on the opposite ends of the body in relation totheY valve seats forming means for enclosing; and protecting said seats, the coupling flanges extending beyondthe valve seats for entirely, receiving the valve body, said 'flanges having a greater diameter than the valve/body and having the kouter endsy thereof' provided with annular internal supporting shoulders for the guide.

In ltestimony thatlI claim-V the foregoing I have Vhereunto set my hand `at Milwaukee, .in the county of=Milwaukee andV State of Visconsin.
